Ascent Trip Report

From E, Okawa campsite, good trails, several tops en route, see GPS track. 11h50 day hike, moving fairly quickly, 4h15 to Iide, 3h round trip to Dainichi, 4h descent (plus half an hour searching for a couple of trig points); most will prefer to use one of the four huts en route.

Left campsite (large car park) 0530 first light, walked out road (barrier, R of toilet block) a short way then fork R at trail sign, uphill thru woodland. Mapped trail fork S of 1485m P66 summit (has a 2nd order trig point) no longer exists, trail passes L of summit, then a good water source (a spring) then at a junction turn L, cross a saddle then steeply up, nice rocky sections, easy scrambling YDS 2+/ easy 3. Shelter hut close to 1644m P29 summit, turn R here, trail passes 2 minor summits, more easy scrambling, passes a 1791m P6 summit (has a 3rd order trig point which I visit on way back), passes a second hut, open stony areas roped off to prevent erosion, climbs to cross 1908m P83 summit, then bigger ascent to Iide east summit, mapped 2102m but outcrop just W of hut #3 is higher, probably 2104m as hand level indicates 1-2m lower than Iide itself, which has 1st order trig with apparently GPS insert in top face. I have this Famous 100 summit to myself in gorgeous weather. Descent SW crossing a minor rocky top, passing some surprisingly permanent looking snow/ice patches facing SSE, pass Onishidake 2013m P57, short trail to its summit, 3rd order trig. Past hut #4 then descent and 250m ascent to Dainichi, highpoint a dwarf pine next to track, marker post to SW a little lower. Summit deserted although a few folk have been out this way today, at least some as far as the summit. SW ridge which I failed even to reach yesterday, has obvious trail along it, apparently at least one steep section.

I head back, Iide still deserted, a few folk passed lower down. I visit the 1791m summit and manage to find trig in bamboo scrub, enjoy the scrambly descent from hut #1, make a small diversion to the 1485m summit and after a search, find its trig in dense tree cover - the only 2nd order Japanese trig I've located (and not found a 4th order).

These diversions cost me probably 45 minutes, I'm back at the trailhead just before dusk. Effectively 11 hour hike vs Naismith formula 10h30, not a trivial hike!
